WOOD-RIM PULLEY.

SPECIFICATION forming petit of` Letters Patent No. 284,133, dated Aug-ust 2e, 1883. Y Application filed May 7, 1883. (No model.) l

To all whom it my concern,

Beit known that I, AUSTIN S. LADD, a citi- Vzen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth 5 of Massachusetts, have invented certain new and useful Improvements in Wood-Rim Pulleys, of which the following is a specification. My invention relates to means of connecting a wooden-rim foundation to a metallic spider IO directly and without the use of screws or bolts and nuts, or other Acommonly-used fastenings. In the accompanying drawings, Figure l is a side elevation of my improved pulley, a part of the lags Or outside fellies being broken away j I to show the ledges at the ends Of the arms' and the middle felly or rim-foundation; Fig. 2, a

central cross-section of the same, taken on the dotted line X X in Fig. 1.

The spider A consists of the hub B and arms 2O B', preferably cast in one piece with the hub 5 but the hub and arms maybe connected in any usual way. Each arm B', on each edge thereof, at or near its outer end, is provided with one or more ledges, C C', whichproject toward the arms next adjacent. A` central wooden felly, D, of the shape of an arc Of a circle, long enough to reach from one arm to the next between said ledges, the ends of the central felly being of such a shape as to fdl the l 3o spaces between said ledges, is insert-ed between each pair of saidrarms and within said ledges to form a rim-foundation, to which lags or Outery fellies, D', may be attached by glue and brads,

or screws, or nails, `in the ordinary manner, the lags being sawed out to the shaperequired, and the rim of the pulley thus formed is finally turned true. The shape of the bearing-ends of the arms may be varied without departing Y from the principle Of my invention. The-cen tral felly forms a foundation on which to build 4o the wooden rim of the pulley, and should be made to fit so `closely between the arms of the spider as to require to be pressed into place. The spider will require no iitting, except boi'- ing out the central hole for the shaft on which the pulley is placed, and except forming the key-seat by which the pulley, if to be used as afast pulley, may be keyedto theshaft. The pulley above described is therefore constructed at slight expense.

I claim as my inventionl. The combination of a metallic spider and a wooden-rim foundation, said foundation and the outer ends of the arms of said spider being adapted to engage directly with each other and to retain said foundation in place, asand for the purpose specied.

2. The combination of the spider, provided with arms having ledges, and the foundationpieces orfellies adapted to reach from one arm 6o to the next, and to be held in place by said ledges, as and for the purpose specified.
